The prize will be awarded every two years, for the first time in 2015, for the best thesis completed by a PhD student in the past two calendar years in the field of high angular resolution optical astronomy at a European institution. This includes adaptive optics, optical interferometry and similar techniques.

Nominations for the first prize must be received by 15 January 2015 at https://olivier-chesneau.oca.eu, where full details about the prize rules are available.

The first winner of the prize will be invited to give a prize lecture in June 2015 during the conference The Physics of Evolved Stars: a conference in memory of Olivier Chesneau in Nice. In addition the winner will receive a cash prize of 1000 euros. ESO will announce the prize winner widely to enhance the visibility of the prize-winning work and also invite the winner to present their work at ESO Headquarters in Garching.

The prize will be allocated by a committee composed of scientists from Nice and other institutes, including the VLTI programme scientist.

Olivier was also very much involved in outreach at different levels and shared his passion and expert knowledge by teaching astronomy and supervised many students and postdocs. He is survived by his wife and two young children.
